MTGS Wikia Article about "New World Order"
Every time I read a comment about "Well if this card had card draw/trample/haste/indestructible/hexproof/life gain...", I think "You're missing the point." They're armchair developer comments that fail to take into account the card's role in the greater Limited and Standard environment. No, it may not be as good as whatever card you're comparing it to. There's a reason for that. Not every burn spell is Lightning Bolt, nor does it need to be or should be.

PSA to everyone who keeps forgetting about the Reserved List:
You're on a website dedicated to talking about MtG. You're only a few keystrokes away from finding out what cards are on the Reserved List. You're also only a few keystrokes away from finding out why some cards on the Reserved List got foil printings in FtV, as Judge promos, or whatnot, as well as why that won't happen again. Stop doing this.

Some interesting things for limited here.
Stealth Mission - I can see this ending a few games, especially when paired with the Wardscale Crocodile, 7/5 hexproof, unblockable. Both commons as well.
Rescuer Sphinx - Base rate of a 3/2 flyer seems good. And quite easily becomes a 4/3 flyer, while resetting an uncommon planeswalker.
Makeshift Battalion - The name is suitably apt, since it has 'battalion' and we see the Boros leading Simic and Dimir into battle.

Guilds dont matter much when the alternative is total annhilation./quote] Doubt that Bolas is thinking about annihilating the plane. He would have planted bombs instead of rising an army and wouldn't bother bringing his own house and lawn ornaments, rather taking control of it after restoring his pre-mending powers.
EDIT: on the other hand, the guilds are not privy to his plans so... Makes sense.

Not strictly better since thrummingbird is blue, rather than white. Also thrummingbird is a common (in Modern Masters 2015 Edition, so it is usable in Pauper). But, yeah, it is a better version (so long as you like White).
